Neural networks have proven apparent success in solving a wide variety of problems. Various engineering applications in particular were studied using these powerful tools.
The Neural network resembles the function of the human brain. A training
process has to be applied first in order that the network acquires knowledge through learning. Then the network can generalize predicted solutions based on the a mount and accuracy of the training data. The target of this research is to develop two neural networks that can predict the productivity of two common construction-finishing activities, which are brick and plaster works. In order to adequately train the networks, 12 projects were used to gather 85 and 100 data points for the brick works and plaster works respectively. These construction projects included residential, commercial, and industrial projects. The gathered data targeted measuring the factors affecting the productivity as well as the related productivity values. Several trials were conducted to choose the appropriate network architecture. Finally 85% of the data was used to train the networks and 15% was used for testing the generalization capability of the networks. The results showing the desired and output values for the testing data were discussed and analyzed. Furthermore, the training data was used again to validate the generalization capability of the networks. The results were also discussed and compared for a predetermined accuracy level. A sensitivity analysis was performed to relate the effects of each of the contributing factors on the productivity values.
